What's wrong?
In NHTSA campaign 16V858, the part at issue is the power sliding door system on 2011-2016 Toyota Sienna minivans. The sliding door motor circuit is supposed to unlatch and move the door only when commanded, then keep the door secured when it is closed. Families rely on that latch control every time passengers sit near the side door.
On included Siennas, the problem starts when the power sliding door cannot open after a command, such as when the door is frozen shut. After that failed opening attempt, the door can later open unexpectedly. The recall addresses the risk that the door opens while the vehicle is moving, which creates a clear passenger safety concern.
There is no warning sign before failure. The first thing an owner notices can be the door refusing to open when commanded, followed later by the door opening when it should stay latched.
Who's affected?
Covers a continuous 2011-2016 Sienna span tied to the same body-door component.

What's the safety risk?
If a rear sliding door opens while the Sienna is moving, occupants face a higher injury risk. Until the repair is complete, confirm the sliding doors are fully closed and latched before each trip and schedule service soon. Repair is free at any franchised Toyota dealer.
What should I do?
- Check your VIN to confirm your 2011-2016 Toyota Sienna is included in this recall.
- Contact a franchised Toyota dealer to schedule the free sliding-door wiring repair: the dealer replaces the junction block and rear sliding door wire harnesses and installs sub wire harnesses so the power sliding doors do not open unexpectedly.
- Bring the recall notice if Toyota mailed one, or reference recall number 16V858 when you call.
- Use extra care if a power sliding door sticks or freezes until the repair is complete.
What happens at the repair
At the dealer, a Toyota technician replaces the junction block and the rear sliding door wire harnesses, then installs two sub wire harnesses. The replacement parts and labor are free under the recall. Toyota's General Reimbursement Plan gives owners who paid to fix this condition before the campaign a way to request reimbursement. Bring prior repair paperwork, receipts, and any payment records to the service desk so the dealer can explain the reimbursement process.
